A Dallas-area teacher who was accused of sending a racially charged tweet about events in Ferguson, Mo., was fired on Friday, school officials said.

Vinita Hegwood, a high school English teacher, was discharged at a special meeting of the trustees of the Duncanville Independent School District, according to a statement emailed by the district.

“In a special meeting this morning, the Duncanville Independent School District Board of Trustees voted unanimously to terminate the teaching contract of Ms. Vinita Hegwood effective immediately,” according to the statement.

Hegwood, who is black, was accused of sending insensitive comments from her personal Twitter account on Nov. 7. She had apologized.
